No, you don’t cast any spells. That’s how normal magic works. If you want to, say, find a treasure, you cast a spell, and try to detect gold. Witchcraft doesn’t do that. If you ask a witch for a treasure, she’ll point at a spot in your garden, and say ‘dig’. And if you dig, you’ll find treasure, because it turns out your grandparents buried it there years ago. It was always there. But it’s the witch who pointed out where to dig.
